Engine
Fuel efficient electronic controlled engine
The Komatsu SAA6D114E engine delivers 155 kW 207 HP
at 1950 rpm. The fuel-efficient, powerful Komatsu engine
makes the D65 superior in both ripping and dozing
operations. The engine is EPA Tier 3 and EU stage 3A
emissions certified. The engine is turbocharged and features
direct fuel injection and air-to-air aftercooling to maximize
power, fuel efficiency and emission compliance.
To minimize noise and vibration, the engine is mounted to
the main frame with rubber cushions.
Hydraulic drive radiator cooling fan
The engine cooling fan rotation speed is electronically
controlled. The fan rotation speed depends on engine
coolant and hydraulic oil temperatures, the higher the
temperature the higher the fan speed. This system increases
fuel efficiency, reduces the operating noise levels and
requires less horsepower than belt driven fan.

Gearshift pattern preset function
When the gearshift pattern is set to either <F1-R2>,
<F2-R1>, <F2-R2>, <F2-R3L> or <F3L-R3L> in the
automatic gearshift mode, the gear automatically shifts to
the preset gear when the travel control joystick is set to
Forward or Reverse position, reducing round trip repetition
work time and operator's efforts. Gearshift pattern
<F2-R3L> and <F3L-R3L> are newly added for high speed
leveling operation.

Palm command hydraulic controlled blade/ripper
joystick
Hydraulically-controlled palm command joystick is equipped
for blade/ ripper control. Combined with the highly reliable
Komatsu hydraulic system, superb control is the result.
ECMV (Electronic Controlled Modulation Valve)
controlled transmission
A controller automatically adjusts each clutch engagement
depending on travel conditions, providing smooth shockless
clutch engagement, improved component life and operator
ride comfort.
Hydrostatic Steering System—smooth, powerful
turning
The engine power is transmitted to both tracks without
power interruption on the inside track for smooth, powerful
turns. Counter-rotation is available for minimum turning
radius enhancing maneuverability.
